Hi,
The iPhone client, when it goes into background, can only respond to
incoming messages.
That makes the Registration expire when there is no communication from the
server before
the expire time. I could make the Registration not expire at all. Not sure
it's the only option.
Is there a way to send a Ping message from server periodically to the
iPhone SIP client. This
will wakeup the SIP client and resend REGISTER message.
Thanks
